OSU Master Gardener training classes offered in hybrid format By Amanda Douridas - OSU Extension Beginning October 2021, Champaign County, in partnership with Miami County, will offer a Master Gardener Volunteer hybrid training to the residents of Champaign, Miami and surrounding counties. The Master Gardener Volunteer Program provides broad instruction in horticulture for enthusiasts of any skill level or interest who then volunteer their time assisting with educational programs and activities for Ohio residents through their local OSU Extension county office. Volunteers are not required to have gardening skills or knowledge; but a passion for learning about gardening and sharing this knowledge with others is a must.
